Set in 1920's Ireland, Gypo Nolan is desperate, he is broke, hopeless and in love with a prostitute, Katie Maddon. The future looks decidedly dreary. An advertisement in a steamship window that guarantees passage to America for £10 attracts his attention. Recollecting that the English are promising a £20 reward for the capture of Irish rebel Wallace Ford, Gypo turns him in. With his new found wealth Gypo begins to draw attention from the other Irish Rebels who suspect him to be the informer. After his capture by the rebels, Gypo tries to escape but is shot as he staggers into a church where he finds Ford's mother praying. As he lies dying she forgives him for her son's death.
